' ler head in Whic Where a coupler isused on the end of a locomotiveequipped with a pilot it is necessary to support the coupler somedistance away from the pilot block, and under such circumstances itbecomes infeasible to emloy the ordinary uncoupling .means. I

ave, therefore, invented animproved and simple uncoupling mechanism forusein connection with the locking pin of a con ler of the knuckle'typeto raise the same. referably the coupler proper is pivoted toaforwardlyprojecting sup ort or draft member mounted on-the pilot lock. As theraisingmeans for the locking pin of the cou ler I employ a lifting leveractuated by suitable manually o erated means and since the coupler mayshift laterally, bein ivoted, it 'is necessary to so mount this li tinglever that it will also turn with the coupler. The lifting lever may beivoteddirectly'to the'cou l scase it also turns with t e coupler, or thelifting lever may be pivoted on-t with means which compel the lever andpivot pin to turn simu'ltaneousl with the shifting of the coupler. Undert ese conditions t is lifting lever is always in operative connectionwith thelocking pin-whereby the latter may be raised by liftingthelever.

I through its lateral flanges 11 to the pilot block or other sup ortt12.The outer or unsupported end 'of tlledraft member-1O is provided with acurved recess 13 adapted to receive the shank of the coupler, and topermit the same toturn on its pivot. A vertical pivot pin 14 passesdownwardly through the outer end of member 10 and through recess -13,and is maintained in place by the collar 15 which rests on the uppersurface of. the member 10 and the transverse cotter 1'6 which preventsthe pivot in 14 from -rising.

The coupler 17 has the or inary knuckle 18,

knuckle pin 19 and a locking pin 20 provided with alongitudinal slot 21.he shank22 of the coupler fits in recess 13, and pin 14 passes throu h around aperture through the shank where y a lateral shifting or turningof the coupler is permitted. On its top end pin 14 has two upstanding saced apertured lugs or STEEL rouNnnrns, or

10 bolted at its rear end' ears 23 between whic is placed and towhich ispivoted a lifting lever 24, having at its free end, which projectswithin slot 21, an u standing proj ectlon 25 which in the elevateconditions of both the locking in andlifting lever strikes a stop 26within s 0t 21 thereby limiting the upward movement-of the liftinglever. On the end of the locomotive or other vehicle and transverselythereto I mounta shaft 27 rotatable in one or more bearings 28 risingfrom. the 'top surface of the pilot block 12. .At its outer end thisshaft has a handle 29 whereby it maybe turned, and at its inner end itis bent laterally to' provide an arm 30 which is connected by'means of achain 31 with the lever 24 atthe point 32.. In order to compel'thelifting lever and pivot pin 14 to turn with the. coupler as the latteris moved laterally the to surface of the coupler head is longitudina lyslotted at 33 so as to provide .a

of the sides of the lever and compels the same and the pivot pin to turnin unison with the coupler whereby the lifting lever is always inoperative connection Witbfthelbcking pin.

- From the illustration. of this invention and V, I

the foregoin description it will be apparent that to lift t e lockinglever so as to permit v is applied thereto between the fulcrum and i theload, and that more power is required to the knuckle 18 to turnon itspin 19 andbe come uncoupled from the cooperating coup ler head, it ismerely necessary to actuate or 'lift the handle 29 thereby turning theshaft 27, lifting arm 30, chain 31, lifting lever 24, and locking pin20. The weights of the parts are such that when handle 29 is released,arm

It may be noted that the lifting lever 24 is a lever of the third orderin which the power raise the lock with this form of lever than would benecessary to directly lift the lock. The pull on the chain 31 must alsobe greater than would be required provided the chain was pulled directlyupwardly above the lift- Ihese disadvantages of this construction areovercome, however, by the construction of the operating shaft 27 and itsarms 29 and 30. In order to lift the locking lever'20- suficiently toperform the uncoupling operation only a comparatively slight elevationof the point 32 of the lever is reqnired and for this reason the arm 30may be made short. Since the arm 29 on the other hand is longer than thearm 30 the mechanical advantage secured by the long arm 29 overcomes thedisadvantage of the form of lever 24.'

In the modification shown in Figs. 3 and 4 the coupler 35 is pivotallymounted 'on the support or draft bar 36 by means of a pivot pin or shaft37 which passes through a portion of the draft bar 36 and through the'ing' suitably apertu red to receive pin 37 Passing transversely throughthe upper ear 38 of the coupler and the upper end of the pivot pin 37 isa horizontal stud sh aft 39 upon which is'adapted to turn the spacedlegs 40 and 41 of a bifurcated lifting lever 42 which projects into aslot of locking pin 20 in front of the center of gravity thereof as inthe pre- 'vious instance. In order to prevent this pivot pin or rod 29from becoming displaced it is provided at one end with a head 43 whilethrough its other end passes a cotter pin 44.

Leg 41 of the bifurcated inner end .of-lifting lever 42 has anupstanding apertured lug 45 which is connected to a chain 46 the latterbeingadapted to be operated, that is lifted and lowered, by any suitablemechanism such, for example, as the shaft-27 witlr it's arms 29 and 30of Figs. 1 and 2.

It will be understood that the lever 42 is pivoted not only to the innerend of the coupler but also to the pivot pin 37 upon which the coupleris mounted. Owing to the rod 39 passing through the pivot pin the latterturns as the coupler is shifted laterally. It

is thus apparent that the outer end of lever 42 always projects into theslot of the locking pin and has, therefore, a constant operativeconnection with the pin.

Although I have described fully the. details of the various forms of myconstruction, to

those skilled in the art it will be apparent that the structures may beconsiderably 1nodified indetails without departurefrom my invention, andwithout sacrifice of any of its benefits or advantages.
